I did a search on PnP upper and lower intake and porting the TB. I get conflicting information. Some say you lose power if it's done wrong. Others say it it's wothwhile as long as you do both upper/lower intake and port the TB. Also if you're automatic it's important to do a VSA delete. Is it really worth it? I know that Type R has done this and he says there are gains. So what's the final definitive verdict?
